Anyone know where or what methanol injection kit I should used for the supercharger from comptech. I am just looking for a kit that will be simple and able to use for this system.

 

and, how I should use this system? like get it filled, how often to use and when to use.

 

There are a run companys in the meth injection game. AEM is one, Snow Performance is another, the trick to a meth system is getting a kit that includes a progressive controler.

You can buy the 50/50 mix from Snow or others or run 100% which you buy at speed/perfromance shops. I have heard a lot of good things about a company called ALKYcontrol that sells meth kits meant for running 100% meth no water.

I am going to use my windshield washer tank for the meth tank and I think it should last about a month dependant on how you drive. I think the tank is 1 gal.

 

ok if i used my windshield washer tank then what other parts do I need, can you tell me where or what I need after I used that?

 

how much is meth for one gallon? would I need to use it if I have a custom cold air intake for the supercharger? also, what about winter time - not use as much?

 

sorry for all of the mass posts, If I were to use my windsheild washer tank should I just reroute the hose to the proper place and just refill the tank as needed since its all set up with lines and stuff?

 

My friend uses a Devils Own kit for his Audi..cheap and effective. You can premix your own. my friend does that to his turbo GS. Works pretty well.

 

It comes in a kit. It turns on by throttle position or boost level. It comes with a reservoir but some people like the extra capacity and stealth look of using the windshield washer bottle.

A progressive controller is preferred to prevent any stumble or transitional knock when it first comes on and tries to choke the engine before full airflow is realized. Progressive turns it on and ramps the injection up progressively depending on airflow.

Meth cost the same or a little more than a gallon of premium fuel if you search around for it.

Your refilling frequency is based on how you drive. When my turbo car was my daily driver I drove it pretty nice, never seeing boost on the way to work and back and a gallon lasted a couple weeks or more depending on how much fun I had on the weekend. There were some nights that I went through a couple gallons at the street races.

Besides the kits mentioned, look at alkycontrol.com. Probably the highest quality components of all meth kits.

 

are these kits universal..they seem to be for certain cars.

 

Usually they are universal. At least all my friends are using universal kits...the ones that have meth injection.

 

Many are universal but that's not a problem. I know when dealing with Julio at alkycontrol.com, he might ask you to take a couple measurements to get the correct hose and wiring length.

 

how much again will some1 with a SC see with meth???

 

You will see a small gain in power but most importantly meth will make it reliable.

 

i gained 20hp/15tq off the meth injection alone (with a good tune of course)

 

this sites gonna make me go broke, but i guess u cant do one thing wihtout the other

 

I'm running the AEM water/meth kit in my car. I've had some very very positive results with the kit.

The install required a little bit of fabrication skills for mounting the pump. I made a stainless steel bracket and mounted it inside the right-front corner of the bumper by the washer fluid tank.

I unscrewed the hose fitting and fluid level sensor from the included 1 gallon tank and drilled some holes in the factory washer fluid tank and mounted them in there.

I mounted the nozzle in the elbow where the throttle body used to be. It's mounted at a 45 degree angle in the elbow in hopes of getting a bitter mixture with the air before entering the intake manifold.

The controller is tucked away under the glovebox. That way it's still relatively easy to get at if I ever need to make any adjustments.

One note with the AEM unit... The sticker on the outside of the controller has tick marks for boost levels... The adjustment pot and the boost tick marks didn't seem to line up on my unit. (The output wire coming from the AEM outputs the right voltage so I know the vacuum line isn't getting pinched.) So I just had to adjust accordingly.

Make sure you get an LED wired in so that you can tell when the pump is running! That'll help you troubleshoot any issues and just verify that all is working properly.

With the standard pulley on the car, I would go through a gallon of water/meth about every 1.5 tanks of gas. (~550 miles) Your mileage will vary based on how heavy your foot is.

The main advantage for me was being able to make more than a couple of WOT runs without heat-soak setting in. Tuning will provide +hp results.

 

Snow Performance Stage II, all day, everyday, I swear by it!!!
